Yeah, you got into Hirata Estate. That's a semi-optional area that's a bit too hard for when you first gain access to it. It's really the game's fault for giving you the bell thingy so early imo.

I definitely recommend giving the game another go. Don't get me wrong, you will die a lot even when you follow the main path like you are supposed to, but the game is a bit more fair with the difficulty curve. Except for the Chained Ogre, that guy is just bullshit.
